Before Zod ever stood face-to-face with Clark Kent, he was a memory. In Smallville lore, Jor-El (Clark’s biological father) didn’t just send his son to Earth; he also banished the entire Kryptonian criminal class to the Phantom Zone.
Long before actor Callum Blue stepped into the role, Zod existed as a phantom—a disembodied consciousness trapped in the Phantom Zone. In the early seasons, specifically Season 5 and Season 6, Zod is the puppet master. Through the vessel of Professor Milton Fine (the incarnation of Brainiac, played brilliantly by James Marsters), Zod manipulates Clark, attempting to secure a Kryptonian body to escape his interdimensional prison.

In the Season 5 finale, "Vessel," the artificial intelligence Brainiac prepares Lex Luthor’s body to serve as Zod’s host.
The introduction of the Phantom Zone was lauded for its creative "crystalline" design and creepy phantoms. The showdown between Clark and a Zod-possessed Lex is often cited as one of the best super-powered fights in the series. In the early seasons, specifically Season 5 and
Adopting the human alias "Major Zod," he leads a team of other reincarnated Kryptonians (including Faora, now in a human host). They believe they are an elite military unit stranded on a backward planet. Their goal? Restore Krypton’s glory by terraforming Earth into "New Krypton."
The dynamic is further complicated by the arrival of the real Kandorians. Zod lies to them about their children and their history to maintain control. Watching Clark
In the Smallville Season 11 comic book continuation (which is canon to the show’s universe), Zod eventually escapes the zone again. He leads a massive Kryptonian uprising on Earth, forcing Clark to finally accept his role as a leader of the Superman Family. He even allies with Lex Luthor.
